Objective This article describes the custom require function so that the browser to implement on-demand loading of JS files, then exactly how to write a library on-demand loading? To implement on-demand loading: This is the function we want to implement require('str.js') when loading the str.js file and creating a function called the Str object, which executes

In the 90 's, many tech companies wanted to find the holy grail of Internet video-on-demand, but they failed. That is because Internet bandwidth is not controllable, user access bandwidth is too narrow, video compression technology immature, server performance is not high, resulting in unsatisfactory quality of video service, no content provider support, there is no market support. Things have improved a lot now. Community broadband, cable TV cable mo

"Change" is the slogan of U.S. President Barack Obama's 2008 campaign for President Obama, the slogan and ideas that coincide with the idea of seeking innovation in 21, the President of the United States.

In practice, this link requires not only the system analyst, software engineer and other computer experts, but also the field experts involved in the relevant fields to complete.Requirements Analysis: This project is a vol

Most people in mathematics and computer languages have always thought that programming and architecture are the greatest part of the entire software life cycle, however, after actual work, we will find that in commercial products, demand analysis is the key to the success of a commercial software. Many of the problems that have emerged in today's software engineering field, such as defects and improper use of resources, are due to unclear requirements

In this project, the demand investigator spent one and a half months opening eight demand exchange meetings and sending more than a dozen demand discussion emails to the subject to investigate the demand, three editions of the Requirement Specification (all over 60 pages) were generated during this period ). After some

Do you remember how many "needs review" you have participated in? Whether you are a host-led, or as a wingman, the "needs of the review meeting" scene is to make people unknown. And the product manager is in this one after another "needs review meeting" in the honed, is a real brush monster upgrade process. It is said that the "demand review", also known as "tearing the assembly", you can feel the picture of the feeling.The Product Manager organizes t

As a software developer, every time the demand analysis ends, we will sigh, how is this requirement completely different from the same as above? As a customer, we can't understand what the difference is between 1-2-3 and 4-4? I think the first problem is that the customer's requirement is to solve the business problem. In the big aspect, the assumption is divided into 1-2-3-4, this is generally okay. If a problem occurs, the customer can agree to ma

Web page Production WEBJX article introduction: recently, perhaps because we interviewed a lot of users to discuss the need to gather more and more topics, as if suddenly we are all of a sudden attention to the product of this process. Of course, there are many methods of demand collection, many predecessors have summed up a lot, can be referred to even moved to their own projects to achieve. These methods are used in large company projects, as long a

Not long ago, Sunny gave Sany Group (Sany Heavy Industry) software requirements related personnel an internal enterprise training on "software demand analysis". The following is the outline of this internal training course (Lite version ): Course description This course will learn the theoretical knowledge and practical technology of software demand engineering, analyze the difficulties encountered in the

First, say happy new year to all the friends in the garden! Last year, I spent half a year at the customer's site working on the project and delivered the project on time. Many incidents occurred during project development, most of which were demand-side changes. Our team was also worried that the project could not be completed as planned. It turns out that these concerns are redundant. As long as there is a good development process, we can embrace ch

The traditional waterfall working mode uses the detailed requirement specification to express the demand, the demand person is responsible for the demand investigation, prepares the detailed requirement specification according to the investigation situation, carries on the request appraisal, after the appraisal signature confirms to the research and development t

Why is it always "demand" in frontFor a long time, the problem has been thought of, software design is not designed in front, but "demand" in the front; Information systems development is not the development of the first but the demand in the front; UML also has an important diagram use case, to conduct requirements analysis The open-close principle in DP is also

Demand Change discussion: Reasons for changes in requirements Reasons for changes in requirementsRequirements include business requirements, user requirements, and functional requirements. Business requirement reflects organizational or customer requirements for high-level systems and products, user requirement describes the tasks that users must complete to use the product, functional requirements (functional Requirement) defines the sof

The following is a statistical result of the demand for developers in three technical fields: Silicon Valley, North America, Australia, and China, the source data comes from the search results of the relevant websites, the data provided by the partners, and the data of the csdn website. We believe that the source data can objectively reflect the comparison between several competing technologies. On the other hand, we can see the distinctive char

Explore angularjs + requirejs to fully implement on-demand loading routines, angularjsrequirejs When performing a project of a certain scale, you usually want to achieve the following goals: 1. Support Complex page logic (dynamically display content according to business rules, such as permissions and data status ); 2. adhere to the basic principles of frontend and backend separation (when there is no separation, pages can be directly generated using

, mock presentations, and more. It is important to note that each communication must be recorded, and the results of the communication can be categorized to facilitate subsequent analysis activities. For example, you can subdivide the requirements into functional requirements, non-functional requirements (such as response time, mean time to failure, automatic recovery time, and so on), environmental restrictions, design constraints, and so on.
